Answer:
A. It shows the same number of atoms of each element on both sides of the equation.
Explanation:
A balanced chemical equation demonstrates the conservation of matter by showing the number of atoms of each element on both sides of the equation or expression.
According to the law of conservation of matter, matter is neither created nor destroyed in the course of a chemical reaction but atoms are rearranged.
- Based on this premise, the number of atoms or moles on both sides of the expression must be equal.
- If there are 3 atoms of carbon on one side, the product must also reflect 3 atoms of carbon.
Answer:
Because they convert the electrical voltage produced by increasing and then it goes into the power lines
Explanation:
Electromagnetic forces occur between electrons and protons while nuclear forces occur between neutrons and protons in the nucleus.
Electromagnetic forces are the forces that are responsible for the attraction between electrons and protons. The electrons in shells repel each other.
The existence of electromagnetic forces explain why positively charged protons repel each other in the nucleus and neutrons are needed to buffer this effect.
The electromagnetic force has a short range. The strong nuclear force applies to the nucleus and focuses on the neutron - proton ratio.
An atom is unstable if it has too many protons because their repulsive force will exceed the nuclear force that keeps them together. Nuclear force is stronger for lighter nuclei than heavier ones.

Answer:
Explanation:
1. First balance the equation for the synthesis of cryolite:
2. Find the limiting reagent between the 
and 
- First calculate the number of moles of each compound using its molar mass and the mass that reacted completely:
- Divide the number of moles obtained between the stoichiometric coefficient of each compound in the chemical reaction:
The 
is the limiting reagent because it has the smallest number.
3. Find the mass of cryolite produced:
